RMAN备份、恢复实验室 之 备份篇 【rman: can't open target】-LMLPHP  
在Linux上,安装完成之后,在测试RMAN时可能会遇到如下错误:
[oracle@smsdbrac1 oracle]$ rman target /
rman: can't open target


这是由于调用的是非Oracle的RMAN的缘故:
[oracle@smsdbrac1 oracle]$ which rman
/usr/X11R6/bin/rman


在X11R6下存在一个名为rman的命令:
[oracle@smsdbrac1 bin]$ ./rman -help
rman
    [-f |||||||||2e||]
    [-S(ource of man page passed in)] [-F(ormatted man page passed in)]
    [-r ] [-l ]
    [-V(olume) ] [-U(RLs as hyperlinks)]
    [-b (show sub)] [-k(eep head/foot)]
    [-n(ame of man page) ] [-s(ection) ]
    [-p(aragraph mode toggle)] [-t(abstops spacing) ]
    [-N(ormalize spacing, changebars)] [-y (zap hyphens toggle)]
    [-K (declare that page has no breaks)]
    [-d(iff) (diff of old page source to incorporate)]
    [-M(essage) (included verbatim at end of Name section)]
    [-R(ebus words for )] [-C (enable Tcl/ formatting)]
    [-o (no op)] [-O (no op with arg)]
    [-q(uiet--don't report warnings)] [-h(elp)] [-v(ersion)]
    []



修正这个问题,我们只需要在Oracle用户的环境变量下,将$ORACLE_HOME/bin放在PATH变量前就可以了:
export PATH=$ORACLE_HOME/bin:${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin


重新登录使环境变量生效,现在Oracle能找到正确的rman了:
[oracle@smsdbrac1 oracle]$ su - oracle
Password: 
[oracle@smsdbrac1 oracle]$ which rman
~/product/10.2.0/db/bin/rman

接下来去登陆一下,看看成功了没有?RMAN备份、恢复实验室 之 备份篇 【rman: can't open target】-LMLPHP
